The regulatory requirements for the properties of road clinker bricks and paving concrete tiles are analyzed The discrepancy is revealed both in the indicators of the normalized properties and their numerical values. The task is to bring into compliance the regulatory requirements for road clinker bricks and paving tiles, taking into account the actual conditions of their operation. Such properties of clinker bricks and paving tiles as compressive strength, bending strength, abrasion resistance, water absorption, acid resistance and frost resistance are analyzed. An approach to the method of testing small-piece road products for frost resistance is considered. The disadvantages of the accepted method of testing clinker bricks for frost resistance, taking into account the features of the brick, are revealed. The nature of the destruction of clinker bricks and paving tiles, which are in real operating conditions in a water-saturated state during freezing and thawing, is analyzed. The discrepancy of the accepted regulatory conditions for testing clinker bricks for frost resistance to the operational conditions is found, and the need to introduce an alternative method for testing bricks for frost resistance is justified. It is proposed to develop a new method for assessing frost resistance for road clinker bricks and paving tiles.
